PUFFiT-X Portable Vaporizer

Hey, sorry for the high number of posts (3rd one in 24 hours). I stumbled upon the PUFFiT-X Portable Vaporizer and I've seen incredibly mixed reviews, some say swear by it yet others say its terrible. I'm not necessarily considering it (probably gonna get a DBV or Solo) but I was wondering what the FC community makes of it. Again thanks for any feedback.
